ROASTING Application filed June 18,

T 0 all whom it may concern:

Be it known that I, EARNST A. Bosrnom, United States of America, residin at Grifiin, in the county of Spaulding an State of Georgia, have invented certam new and useful Improvements in Roast-' following is a specification, reference being. had therein to the accompanying drawing.

My invention relates to means for remove ing' the skins from vegetables andmore particularly to means for removingthe skin of pimento peppers by roasting or singeing. he main object of the invention is to provide a roasting machine which will continuously and automatically carry out the roasting process on a large scale with uniform results and capable of being adjusted to bring about the results required.

Other objects of the invention will be a perusal of the following I specification and drawings accompanying the same.

My invention is illustrated in the accompanying drawings in which:

'Fig. 1 is a plan view of the' roaster;

Fig. 2 is a side view of the roaster;

Fig. 3 is an end view of the roaster cut on the line 3-3 of Fig. 1' with the guar removed and looking in the direction of the arrows;

Fig. 4 is an enlarged sectional view of the as furnace on the line 4 -4 of Fig. 1,

[looking in the direction of the arrows showing the position of the gas burners, whic enter alternately on opposite sides of the bottom-of the furnace, as hereinafter explained;

Fig. 5 is a detail sectional enlargement of which takes the pimentos through the furnace and Fi 6 1s a section taken on the line 66 The main frame 1 is .fabri'cated' from angle iron of suitable size alhd strength, said angles being bolted and riveted together, so as to form a strong and substantial frame-- furnace and moving parts of said machine.

A gas furnace 2is located as shown on one side of the framework. This furnace is built u of fire brick as shown in detail section, ig. 4:, having a slot lengthwise through the furnace, for permitting the carrier rods to pass through from one end of OF GRIFFIN, GEORGIA, GRIFFIN, GEORGIA, CORPORATION OF GEORGIA.

the fixnace to the other. In practice this furnace is about fourteen feet in length, and live by even inches in internal cross section, wit gas burners entering the bottom just b the sides, and alternating first one side a (1 then the other, about nine inches apart, forming a the whole len th of-the furnace for the purpose of quick y and completely burning up the skin on said pimentos when through the furnace on inafter described.

For the purpose above mentioned of carrying the pimentos through the furnace, an endless chaincarrier is constructed, composed of a series'of cast ironframes 3 as shown in partial section, Fig. 5, having an upright rotatable shaft 4 with a pear-shaped form 5 on its upper end, for holding the pimentos, said shaft being suitably supported in frame 3 by a bearing or step at the bottom end of said shaft 4, and a bearin two-thirds of the way up as shown. bai cast iron frame?) has a stationary pin or shaft 6 inserted at its lower end as shown, ose of taking the grooved guide roller 7 whlch is-held on to said shaft with a cotter pin as shown. The cast earns the carriers, as herechain bolted to same at suitable distance 5. These (K') attachments when linked up with two plain chain links between each frame, form the endless carrier before rnentioned, the guide roller 7 along both sides of the machine as shown, and connecting at each end with a platform 29 suitably supported and connecting with said track so as to support and guide said rollers on to track 28.

continuous flame iron frame d 3 has two (K) attachments of link belt To actuate this endless carrier, two suitable sprockets 8 are keyed on to the upright shaft 9 suitably spaced to engage the link belt chain and attachments bolted to said carrier 3 and forming the driving shaft'for the carriers at the head end of the machine. A corresponding pair of sprockets is carheld in a take-up device 11 having a hand wheel nut'and screw X for the purpose of keepingv the chains of the carrier at proper tension at all times.

Motion to this upright shaft 9 is derived from the jackv shaft 12 carrying a bevel pinion on one end, engaging a bevel gear on end of the mainframe,

the

the upright shaft 9, said jack shaft 12 receiving its motion through suitable sprockets and chain, from the intermediate shaft 13, which in turn receives its motion from the variable speed shaft 14, carrying a friction disc 21 at one end engaging a friction pulley 15 on high speed driving shaft 16, which carries the tight and loose driving pulleys 17 and 18. A variable speed is obtained by turning hand wheel 19 which through worm 20 moves friction pulley 15 out or in on friction disc 21.

Intermediate shaft 13 extends to foot or opposite end of themachine. At this end of the shaft 13 it carries a sprocket 22, which through a suitable sprocket chain and gears revolves the brush shaft 23, which serves the purpose of removing the pimentos from the carrier as shown at 24.

The operation of the roaster is as follows: e as and air pipes are first connected with the proper gas and air supply as shown in Fig. 2, the flame being adjusted in the furnace by the regulating valves 26;

and 27 provided as shown. Motion is then given the carriers b shifting the drive belt on to the tight pul ey 17, which starts the carrier chain moving. The pimentos having had the seed core removed, are placed on the carriers at the foot of the machine as shown at 25 in Fig. 2, and are then moved into the furnace fire by the carriers. The intense heat puifs the skin away from'the meat or body of the imento, and is burned into a smut or comp etely destroyed by the hot fire. The speed or time required for the destruction of the skin, is regulated by the hand wheel 19 as is also the intensity of the fire by the valves 26 and 27. After passing through the furnace, the pimentos are ra ually cooled oil by the time they reach rush 23 when the revolution of brush 23 removes them and they drop into the box or receptacle as shown at 24, from whenofe the pimentos go to the washer to have the burned skin Washed ofl'.

I claim:

1. A. roasting machine having a combination of a gas furnace, a carrier chain for conducting pimentos through the furnace,

a rotating brush for removing the pimentos from the carriers, and a regulating device for controlling the speed of said carriers, substantially as set forth.

2. A roasting machine for the purpose described comprising a roasting chamber, an endless chain of carriers arranged to be driven through said chamber, each of said carriers comprising a vertically arranged rotatable shaft having a holder adapted to fit into and support a pimento pepper against lateral and downward displacement, and driven means outside of said roasting chamber for removing the pimento pepper upwardly from off said holders.

3. A roasting machine comprising a furnace open at the bottom and ends, means for introducing gas for combustion in said furnace from beneath and in an upward direction, and carrier elements traveling through said-furnace with means for supporting same from beneath.

I 4. A roasting machine comprising a furnace having continuous side walls and open arch, an opening extending the length of the furnacein the bottom part thereof, a carrier traveling beneath said opening, means on said carrier extending into the furnace for supporting fruit or vegetables therein, and means to supply gas for combustion in said furnace along the side walls in an upward direction.

In a roasting machine for peeling fruit, a sin eing furnace, a fruit carrier for carrying ruit therethrough, driving means for said carrier and means for regulatin the speed of said carrier independently '0 said driving means. 6. In a roasting machine for peeling fruit, the combination of an elongated furnace, fruit conveying mechanism mounted below and outside the walls of said furnace, and fruit carriers extending from said conveying mechanism into the furnace, said extension carriers having no relatively moving parts.

In testimony whereof I allix my signature.
